Helium Emerges from the Sun: 1868 Eclipse Unveils a New Element

On Aug. 18, 1868, during a total solar eclipse in India, French astronomer Pierre Janssen used a spectroscope to observe a bright yellow line not matching any known element, signaling the discovery of helium; English astronomer Norman Lockyer independently identified the same line as a new element, later named helium after Helios. This was the first time spectroscopy revealed an element in an astronomical object before it was found on Earth, and helium would later prove essential for spaceflight and stellar physics.

Helium: The Sun's Element That Was Found Before Earth

During the 1868 solar eclipse, Janssen’s spectroscope revealed a bright yellow line in the Sun’s spectrum that did not match any known Earth element, leading Lockyer to propose a new element named helium after Helios; it wasn’t isolated on Earth until Ramsay’s 1895 work, making helium the only element discovered in space before it was found on Earth and showcasing how spectroscopy lets astronomers read distant chemistry.

Japan grapples with ADHD drug shortage as demand surges

Concerta, an ADHD medication from Janssen, has been in nationwide short supply in Japan since last fall, with clinics unable to prescribe it to new patients and restricting long‑time patients to about two weeks’ worth. Janssen previously said stock would be resolved in about two months, but shortages persist and full restoration is expected to take many more months. Concerta is one of only three ADHD drugs approved for adults in Japan, a concern as the adult ADHD population grows.
